After first looking at property in Tenn, my wife and I ended up in KY after we started getting emails from United Country realtors. We thought that the prices were a bit less for more home and land.
While we have had a couple of EF1 and EF2 tornadoes in our area of south central KY, mostly it seems like the worst weather tracks along the Ohio river area or to our south in Tenn. So, look for a home with a basement. Also, do get a good inspection including radon before your purchase. Zoning and codes can be non existent.
Wages will be commensurate with taxes. I am not sure about all KY counties but mine bases property taxes off of the property purchase price. There is no vehicle inspection but there is a yearly luxury tax when you register. But then gas is reasonable as are registration fees in general. There is no SS or pension tax. In spite of what you may read about our health rating, I find the health care to be excellent. While water and air do play a role, it is more likely to be lifestyle that contributes. No place is an island, there are drug and related crime issues. On the other hand, you need not be afraid to defend what is yours.
